Correct Answer (Detailed Explanation is Below)
A.
25
Detailed Explanation
Answer: (A) 25
The expression &x obtains the address of variable x and stores it in pointer p.
The dereference operator *p accesses the value stored at the address held by p.
Since x = 25, dereferencing p gives 25.
Therefore, the output is 25.
